My 50SBX70B flicks than lost the power

My 50SBX70B start flick than lost the power now and then since last week. And It is getting more often.

It happen randomly in any time of day, when TV start flicks horizontally, it will later lost the power and turn itself off. I tried to unplug to reset and it back to normal couple times. Sometime the screen is not back but we can hear the audio part working just fine. It is happen several times a day now. We did not use this TV a lot. Wonder if there is easy way to fix it. I can do some simple parts replace job. I need the help to identify which to replace.

Can anyone help me about that? Many thanks.

Flicking standby

Power supply is developing a problem sustaining voltage regulation and is programmed to shut down. Or it could be a bad OP-Amp on the interface board that's not closing when voltage is applied. Your tv needs servicing. You can send it too us or at your local tv repair shop for proper troubleshooting and repair.
